Description The search for materials to treat wastewater is especially crucial. Herein, we have prepared 1D molybdenum oxide (MoO3) nanobelts through a hydrothermal approach. The binary (MoO3/SiO2) and ternary composites of MoO3/SiO2/MXene were synthesized via ultrasonication route. The as-prepared MoO3, MoO3/SiO2, and MoO3/SiO2/MXene composites were employed to investigate the photocatalytic behavior of two organic dyes, methyl orange (MO) and crystal violet (CV). The % degradation of MO in the presence of MoO3 nanobelts and MoO3/SiO2 was calculated to be 48.9% and 74.4%, respectively. In the case of CV dye, the degradation (%) was observed at 53.7% and 75.9%. The MoO3/SiO2/MXene composite revealed the best photocatalytic behavior against both MO and CV dyes by removing 94.7% and 97.7% under visible light irradiation. The rate constant values of MoO3 nanobelts, MoO3/SiO2 and …
